Kern OCM 161 Inverted Trinocular Halogen Phase Optics

Description

Document unstained living tissue cultures inside deep culture flasks using the Kern OCM 161 Inverted Microscope. Powered by an infinity-corrected IOS optical system, it delivers 100x, 200x, and 400x magnification via four Long Working Distance (LWD) Plan Achromatic objectives: 10x/0.25, 20x/0.40, and 40x/0.60 brightfield lenses, plus a specialized 20x/0.40 Phase Contrast (PH) objective. The inverted design lets researchers inspect adherent cell lines directly through vessel bottoms without disturbing liquid media.

Transmitted illumination is supplied by an overhead swiveling arm housing a powerful 6V/30W halogen lamp, focused through an LWD condenser (NA 0.30) with 72 mm of vertical clearance and an adjustable phase ring slider. The 45-degree inclined trinocular head features high-eyepoint HWF 10x/22 mm eyepieces and a straight vertical photo tube with a selectable 100:0 visual / 0:100 camera beam splitter. The large 210 x 241 mm fixed stage includes modular insert rings and a detachable universal mechanical specimen holder with 120 x 80 mm XY travel, supported by a 12.0 kg cast-metal frame with 2-micron coaxial focus graduations.

Key Features of Kern OCM 161 Inverted Microscope

A professional inverted biological trinocular microscope engineered for cell culture monitoring, oncology research, and IVF evaluation clinics. Combines four Infinity Plan LWD objectives with an LWD 72 mm clearance condenser, 30W halogen lighting, vertical camera port, and a 120 x 80 mm mechanical stage.

• Inverted optical path allows direct cellular observation through culture flask bottoms
• Infinity Plan Achromatic LWD objectives: 10x, 20x, 40x, plus specialized 20x Phase Contrast
• LWD inverted condenser (NA 0.30) provides 72 mm of vertical clearance for tall vessels
• Overhead 6V/30W halogen lamp module with continuous analog rheostat rotary dimmer
• Top-mounted vertical trinocular photo tube with selectable 100:0 / 0:100 optical beam splitter
• Large 210 x 241 mm stage with detachable mechanical specimen holder (120 x 80 mm XY travel)
• High-eyepoint HWF 10x/22 mm widefield eyepieces with bilateral diopter adjustment rings
• Solid 12.0 kg cast-metal chassis provides complete vibration-free benchtop stability

Infinity Plan LWD Optics & Phase Contrast Contrast

Transparent living cells and micro-organisms lack natural pigmentation, appearing invisible under standard brightfield light. The specialized 20x LWD phase objective and matching condenser slider ring shift light wave paths, converting subtle refractive index differences into sharp grayscale contrast without toxic chemical dyes. The long working distance design compensates for vessel bottom thickness, keeping cell monolayers tack-sharp.

72mm Overhead Clearance & Trinocular Camera Output

With 72 mm of vertical clearance beneath the condenser, loading tall culture flasks and roller bottles is fast and spill-free. The swiveling lamp house swings backward smoothly to provide unobstructed access for micromanipulation needles and pipettes. The straight vertical photo tube routes clean optical data to external digital C-mount cameras, letting cell biology teams record live time-lapse footage while actively observing specimens through the oculars.

• Swiveling overhead illumination arm clears space for bulky roller bottles and pipettes
• Vertical camera channel allows seamless digital video recording and defect archiving
• Detachable XY mechanical stage provides 120 x 80 mm travel across micro-well plates
